What type of number can be written as an a fraction a/b where a and b are Integres and b is not equal to zero?

Integers, Terminating Decimals, Recurring Decimals, Proper and Improper Fractions.

Step-by-step explanation:

The following subset of the real number system can be written in the form , b≠0.

Integers(ℤ): These are positive and negative whole numbers. For example, 5 can be written as

Terminating Decimals: These are fractions that when converted to decimal numbers have an end.

e.g.

Recurring Decimals: These are fractions that when converted to decimal numbers do not have an end.

e.g.

Proper Fractions: These are fractions of the form where a<b. An examples is

Improper Fractions: These are fractions of the form where a>b. An examples is

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
